have been obtained with like quantities of nitrogen supplied 

 in the form of sulphate of ammonia, Peruvian guano, rape 

 cake, &c. 



It is not, of course, to be supposed that any hop-grower 

 would year after year use, as we are using, nothing but 

 phosphates, potash, and nitrate of soda in his hop gardens. 

 Miscellaneous feeding is probably good for plants as well as 

 for animals, and the quantity of nitrate of soda to be used in 

 a system of miscellaneous manuring will obviously depend on 

 the quantity of nitrogen supplied in other forms. 



In addition to our purely chemically manured plots, 

 however, we have had each year, for purposes of general 

 comparison, a trial plot manured solely with dung, and inci- 

 dentally we have been able also to institute comparisons 

 between the yield of our various experimental plots and the 

 yield of the remaining portion of the field, and sometimes 

 with the yield of certain othe parts of the farm, obtained 

 under miscellaneous manuring similar to that followed in 

 ordinarily accepted hop-growing practice. 



Our experiments began at the end of 1894, when a garden 

 of young Fuggles hops, about to enter the first year of poling, 

 was selected for the purpose. Our experimental plots are 

 each one-sixth of an acre in area, and they run parallel with 

 one another, there being four rows of hills in each. During 

 the first season all the plots were limed and dunged. In the 

 second, third, and fourth seasons no dung has been used on 

 six of the plots, which have been treated with purely chemical 

 fertilisers, phosphates having been abundantly supplied every 

 year in the alternating forms of superphosphate and basic 

 slag. Potash also has been supplied kainit in 1895, niuria e 

 of potash in 1896, sulphate of potash in 1897 an d 1898, an 

 kainit in 1899.
